Why does my dog's tongue seem stuck or swallowed? Is it serious?

He has a very short snout, so this may be because his tongue is too long and there is not enough space for his tongue inside the mouth. This is very likely, especially if he can freely move his tongue. If his tongue appears paralysed you need to take him to your veterinarian for an exam to find out why. There could be various reasons for this.

Very cute puppy. It is possible that she is sticking out her tongue due to positioning of her teeth. IF she were to have malocclusion (teeth abnormally positioned) it could allow her tongue to slip out. It could also just be a puppy things she grows out of. Good luck with the puppy

Depending on which teeth and how many are removed it is not uncommon for some dogs to not be able to keep their tongue in after extractions. This can also be a nervous behavior or a sign of nausea. It is unlikely neurological if there are no other signs such as difficulty swallowing or blinking or any changes in facial symmetry

Puppies this small don't have teeth to keep the tongue in the mouth, so it's common to see them sticking their tongue out a little. However, this does seem to be out a little more than normal, which may indicate that he has an overly large tongue for his snout. I wouldn't worry too much about this right now unless he is having difficulty suckling or other issues. It's definitely possible that it won't stick out as much as he ages. You can have the vet evaluate him better when you take him in for his first vaccines around 6-8 weeks of age. I hope that helps and all is well with your pup.

Thanks for using Petco Pet Education Center, formerly Petcoach! Without seeing Crystal it is hard to say what is going on. She could be nauseous but typically dogs have a decreased appetite with that. I would also be concerned about a bad/infected tooth. I recommend taking her to a vet for a good oral exam. They may need to do further diagnostics to determine the cause. Good luck and kisses to Crystal!

Usually when a dog can only stick his tongue to one side it's either a structural problem of the mouth cavity or a neurological problem (in the brain), i would recommend taking him to the vet in order to have this issue checked, i'm not sure there will be a solution for this problem though.

Some breeds can have naturally darker tongues, but this looks more like the tongue was bruised or scraped/burned. (Or she licked/ate something that would stain the tongue such as berries) Some illnesses that involve circulation or organ function can also cause the tongue to appear bruised or painful, as well as ingestion of substances that could affect organ function. If she is showing any signs of illness in addition to the change such as vomiting or diarrhea, lethargy, etc, the tongue is very painful or bothersome affecting her ability to eat, she got into something she shouldn't have, or she seems to be having trouble breathing/gasping for air, seeking veterinary care ASAP is best.
